North Carolina experiences all types of dangerous weather: Tornadoes, hurricanes, ice storms, snow, flooding, etc. As long as you are acting in the course and scope of your employment, you may likely receive workers' compensation if your injury is clearly work-related.
You may not necessarily have a job that requires you to be outside. You may not necessarily be at work when your compensable injury occurs. What if you were required to ship a package for your employer? Perhaps a tornado hit on your way to the post office. This is likely covered by North Carolina workers' compensation, pending your employer has proper insurance. (Learn what to do if your employer does not have workers' comp insurance.)
